A water hose coupling having a swivel grip is provided. A first coupling portion with a male threaded end integral with a first larger diameter base is connected to a second coupling portion through a freely rotating connection. The second coupling portion includes a second larger diameter base. The second coupling portion further includes a coupling protrusion integral with the second larger diameter base. The coupling protrusion may have one or more barbs to interface with a hose or a threaded female coupling to interface with a male threaded connector. The coupling is connected to an end of a hose to which accessories may be attached. An outer sleeve is connected to the first larger diameter base of the first coupling portion and can freely rotate with the first coupling portion around the remainder of the apparatus and hose. The outer sleeve acts as an ergonomic grip for users to hold and rotate when using the hose and installing accessories.

A fuel line connector assembly that includes first and second connectors. The first connector includes a ramp having an inner core and an outer skin surrounding at least a part of the inner core. The inner core extends through the ramp at a location adjacent a radially extending retaining surface for at least a portion of the radial extent of the retaining surface. The second connector has a hook wherein, when the first and second connectors are brought together and secured to each other, the hook inhibits separation of the first and second connectors by bearing again the retaining surface. The first connector is made by coinjection molding a connector body having the outer skin and inner core with the inner core extending through the ramp to a sacrificial portion, and then severing the sacrificial portion from the ramp leaving the inner core exposed at an apex of the ramp.

A fluid supply line is provided to reduce the labor and cost required for dripline system installations by providing predetermined fitting locations where driplines can be attached. The supply line consists of a conduit having a side wall, a connector extending through the side wall of the conduit, the connector having a conduit connecting segment extending outside the conduit and an inlet segment extending into the conduit, and the inlet segment being connected to the side wall of the conduit.

A tubing junction assembly may include a body, and a collar coupled to the body. The body may include a head portion, a base portion, and an intermediate portion. At least a portion of an outer surface of the body at the intermediate portion may define a cross-sectional width that tapers from the head portion to the base portion. The collar may have an inner surface defining a passage. A tubing may be stretched over the outer surface of the body with a proximal end portion of the tubing stretched over at least a portion of the outer surface of the body at the intermediate portion. The inner surface of the collar may be sleeved over a portion of the outer surface of the tubing and coupled to the collar such that the proximal end portion of the tubing is sandwiched and compressed between the body and the collar.

A fluid connection set includes a connector (1), a flexible hose (2), and a crimping collar (5) for fixing the front end of the flexible hose to the connector, the connector including a connector body (10), a tubular nozzle (3), the tubular nozzle including retaining radial projections (31) of the hose as well as a clamping area (30) of the hose, and a temporary accommodation space (4), arranged between the tubular nozzle (3) and the connector body (10), for housing the collar during the operation of inserting the flexible tube, after which the collar is moved with respect to the clamping area and then crimped.

A fuel line connector assembly that includes first and second connectors. The first connector includes a ramp having an inner core and an outer skin surrounding at least a part of the inner core. The inner core extends through the ramp at a location adjacent a radially extending retaining surface for at least a portion of the radial extent of the retaining surface. The second connector has a hook wherein, when the first and second connectors are brought together and secured to each other, the hook inhibits separation of the first and second connectors by bearing again the retaining surface. The first connector is made by coinjection molding a connector body having the outer skin and inner core with the inner core extending through the ramp to a sacrificial portion, and then severing the sacrificial portion from the ramp leaving the inner core exposed at an apex of the ramp.

Spigot device including a spigot formed with exterior gripping teeth and sleeve device to telescope over the spigot. The sleeve device is formed with a radially inwardly opening, distally contracting conical bearing surface which mounts a radially inwardly contractible gripper ring device captive therein, and constructed to be driven radially inwardly by the bearing surface as the sleeve is drawn proximally on the spigot to grip a plastic pipe trapped in the annulus between the sleeve and spigot.

The steps of selecting a spigot device including a distally projecting spigot of a predetermined outside diameter. Selecting a sleeve device formed with a radially inwardly opening interior retainer collar with an interior distally extending and radially and inwardly sloped bearing surface defining a gripper ring cavity. Selecting a gripper ring device which is contractible radially inwardly and inserting in the cavity and retaining the gripper ring device in the cavity to cooperate with the outside diameter to form an annulus for receipt of the plastic pipe and causing the gripper ring device to grip the pipe.

A clamping connection for pipes made of polymer material or made of composite materials, containing a connection piece, which has a supporting sleeve for the sliding on of a pipe to be connected and which is bounded at one end by a stop collar, wherein a sealing element is arranged on the supporting sleeve, wherein the clamping connection also comprises a clamping sleeve, which is captively connected to the stop collar of the connection piece before the pipe installation, wherein a pipe inserted onto the supporting sleeve is clamped by sliding the clamping sleeve over the pipe in a direction opposite to the insertion direction of the pipe.

A motor vehicle assembly unit having a connector, in particular a quick connector, and having a motor vehicle fluid line, wherein the connector includes an insertion end for inserting the fluid line, wherein there is a securing spike on the insertion end, which is encompassed by an outer sleeve. An annular insertion space for the fluid line or a fluid line end of the fluid line is disposed between the securing spike and the outer sleeve. The outer sleeve is connected to the securing spike by means of at least one break-away element, that breaks when the fluid line is inserted in the annular insertion space, such that the outer sleeve can be slid onto the securing spike, or further slid onto the securing spike from, or with, the fluid line.
